GLASS SEAT FOR BALL-VALVES.

SPECIFICATION forming' part 0f Letters Pte-1lb NO. 728,380, dated. May 19, 1903. `Application iiled November 1, 1902. Serial No. 129,772.' (Nolmodel.) i

To all whom it may coz/werft:A

Be it known that I, LEWIS W. EGGLESTON, a citizen of the United States, residing at Appleton, in the county of Outagamie and State of Wisconsin, have invented certain new and useful Improvements in Glass Seats for Ball- Valves; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had'to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in valve attachments, and particularly in the provision of a glass seat for a ball-cock; and it consists in the provision of a metallic tubing which is chambered out and adapted to receive a glass tubing, the end of which tapers slightly to fit securely against a shoulder formed in the metallic tubing, the upper end of the glass tubing adapted to form a seat for a iioat-actuated valve.

The invention consists, further, in various details Yof construction and combinations of parts, which will be hereinafter fully described and then specically definedin the appended claim.

My invention is illustrated in the accom-A panying drawings, which, with the letters of reference marked thereon, form a part of this application, and in which drawings similar letters of reference indicate like parts in the views, in which- Figure 1 is a central vertical section through lmy invention, showingthe glass valve-seat.

Fig. 2 is a view showing parts of the device disassembled and illustratingl the shape of the glass tube.

Reference now being had to the details of the drawings by letter, A designates the valvechamber, having a valve B, the stem of which is apertured near its upper end to receive a lever C, pivoted at oneend to bracket-arms on the wall of the valve-chamber, and D designates a lever which isconnected to the lever C by means of a linkE. The outer end of the lever D is adapted Vto be connected to a iloat-stem, and bymeans of the angled arm G the latter may be held in dierent positions by means of the adjusting-screw H, which works in an elongated slot D in lever D. The original brass seat L has inserted in its lower end a flanged tubing L, on the upper end of which the glass tubing M rests, which latter Vhas its upper end M tapered. A gasket is `observed that the same may be easily removed by simply detaching the parts and maybe replaced by another when desired.

While I have yshown aparticular construction of device embodying my invention, it will be observed thatl may make alterations in the construction ofthe same without departing from the spirit of the invention.

Having thus fully described myinvention, what I claim asnew, and desire to secure by Letters Patent, is-

In combination with a valve-chamber having anv integral tubular extension, exteriorly threaded at one end, and its other end projecting into4 said chamber, a valve mounted in a contractedportion of said chamber and provided with a valve-block seated in a recess in the lower end of. said valve,"a lianged thimble,an interiorly-threaded union having ashoulder formed at the inner.. end,v of the threaded portion on which shoulder the flange of said thimble is adapted to rest, a packing intermediate the lianged end of the thimble and the threaded end of the extension of the valve-chamber, a thimble L' telescoping Within the thimble L and having a flange iitting against the end of the thimble L and ush with the circumference thereof, andan openended glass tubing N resting lon the inner end of the thimble L', the upper end of said ICQ glass tubing adapted to form aV seat for said valve-block, as shown and described.

In testimony whereof Ihereunto aftixlmy signature in presence of two witnesses. LEWIS W. EGGLESTON.
